jakeoster Posted October 21, 2010 Share Posted October 21, 2010 I was going to upgrade my stock fuel tank and use a fuel cell. From what I have seen one must cut out the spare tire well and have it sit half inside the cabin and half below it. Now my concern is that being a unibody, removing such a chunk might make the chassis less rigid and may compromise the structural integrity of the car (RB25 240z & occasionally a hard driver on the track). What reinforcements would be a good choice without going deep into the wallet. I have a welder but no tube bending capabilities? Thanks.

JMortensen Posted October 21, 2010 Share Posted October 21, 2010 The spare tire well is in the middle of a boxed in structure. There is a frame rail behind, on both sides, and in front. You won't be compromising anything. FWIW, the stock tank is lighter and would be lower than what you're planning. Both good things for go fast cars. A "real" fuel cell for road racing with a steel can and plastic bladder weighs A LOT more than the tank, so if you're not going to gain anything and you'll add 20 or more lbs, don't do the fuel cell is my advice. If the rules require it, then go for it and don't worry about structural integrity. Quote Link to comment Share on other sites More sharing options...
